Why is it important that the seedling’s true leaves grow quickly?HURRY IM BEING TIMED
to help disperse seeds to areas where they can grow
to shield the seedling from too much water or rain
to protect the seedling from receiving too much sunlight
to make food for the seedling’s continued growth
Answer:
The correct answer is - to make food for the seedling’s continued growth.
Explanation:
The true leaves that emerge from the seedlings are the leaves that are capable of performing photosynthesis and start generating food and energy. These support the plant for the rest of its life in terms of food and energy.
Seedlings grow from the soil, two leaves in beginning called cotyledons that are not the true leaves and not able to perform photosynthesis and generate their food for the seedling’s continued growth.
Explain why index fossils are important.
Answer:
Index fossils are used by geologists and palaeontologists as significant aids to determine the correlation and age of rock formations. Geologists use large fossils or macrofossils and microscopic fossils or microfossils as indices to define and identify geologic periods.

In what period did fish, mammals, reptiles, amphibians, and plants appear on earth?
Explanation:
In Cretaceous Period,fish mammals,reptiles,amphibians,and plants appeared on the earth.
The Devonian Period lasted 417 million to 354 million years. Ammonites, starfish, corals, crinoid stems, armored fish, sharks, early bony fish, and early amphibians were among the living things during the Devonian Period.
What is Devonian Period?The Devonian, a Paleozoic era, is also known as the Age of Fishes because it produced a diverse range of fish.
The most fearsome were the armored placoderms, a group that first appeared during the Silurian period and had powerful jaws lined with bladelike plates that acted as teeth.
Throughout the Devonian period, the Earth was hotter and drier than it is nowadays.
Warm and equatorial climates were widespread, as evidenced by the abundance of evaporite basins in the Northern Hemisphere, coal deposits in Arctic Canada and Spitsbergen, as well as pervasive desert circumstances and carbonate reefs.
Dunkleosteus terrelli was the largest species and most likely the largest fish in Devonian times. It could eat almost anything because it was one of the largest and most powerful fish ever.
Thus, the fish, mammals, reptiles, amphibians, and plants appeared on earth in Devonian Period.

Which of the following is lost to the environment as heat so that it cannot be continually recycled?
Group of answer choices
oxygen
nitrogen
phosphorous
energy
Answer:
Energy
Explanation:
Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.
